Serch text

How can i find a text ( included a drawing) in many, many files extensions
.. dwg or dxf.
Thanks

 

In dwg with AutoLISP:

(ssget "X" (list (cons 0 "TEXT")
and then looking for and processing the text
in that selectionset.

In dxf it is more complicated, because you have to
look for the multi-lined Text-entity in the entities section.

How interesting, I have just posted some info on our product in an
other thread.

I recommend to use a standard search indexing tool. If you have
Windows installed (W2000+) you have MS Indexing Service allready
installed in your system. Personally I like WDS 3.0 much better
(Windows Desktop Search).

However, by default the search indexer just cannot access the dwg
files. This is why the IFilter format is designed, so 3rd parties can
provide the reader tool to access the specific files. We have
developed a DWG IFilter here at CAD & Company.

The DWG IFilter is developed to be used by search indexers such as
Windows Desktop Search or SharePoint. The IFilter serves as a
translater and will read the textual contents from the file for the
indexer tool. Then you can very efficiently search trough all indexed
files.
The text that we extract for indexing includes all actual Text, Mtext,
Attribute values, names, referenced file names, block names, and more.
You can set the tool to include less or more kinds of objects.

The new version is able to read files up to AutoCAD 2007 and 2008 -
and is expected to be released in a couple of weeks. A free trial will
be available, also it is free for non-commercial desktop use. For now,
you can start testing with our 2005 trial DWG IFilter, available at
www.cadcompany.nl/ifilter

Good luck, I'd like to hear from you if this helps you out.
